A series of metals are arranged on the basis of reactivity and is said to be reactivity series . Electrolysis Potassium K Strontium Sr Calcium Ca Sodium Na Magnesium Mg Displaces H2 gas from steam and acids and forms hydroxides. (ii) For obtaining metals that are in the middle of reactivity series, oxides of such metals can be reduced with coke (carbon) which acts as a reducing agent. This is known as displacement reaction. In the same way that metals can be ordered in terms of reducing strength, the non-metals can be ordered in terms of their oxidising strength. Before discussing the reactivity order of metals, it is important to discuss about the differences between metals and non-metals. For example, iron (III) oxide can be reduced to iron, as follows : (iii) For obtaining metals that are high up in the reactivity series, their oxides are reduced to metals by electrolysis. Reactivity of element decreases on moving from top to bottom in the given reactivity series. Lithium Li Displaces H2 gas from water, steam and acids and forms hydroxides. ... All the elements belonging to lanthanide and actinide series are f- block elements which are also known as inner- transition elements as it is a transit to move from the transition elements of Group IIIB to Group IVB. Reaction will not take place as Fe is below Zn in the activity series and cannot displace Zn from its solution. I. Reactivity Series of Metals. The halogens are a typical example of a non-metal reactivity series. In the reactivity series, copper, gold, and silver are at the bottom and hence are least reactive. The order of intensity of reactivity is known as reactivity series. Place in order of reactivity: potassium, sodium, calcium, magnesium, zinc, iron, hydrogen and copper, by reference to the reactions, if any, of the elements with: water or steam; dilute hydrochloric acid (except for alkali metals) Reactivity of Non- Metals. ... Non-metals. II. These metals are known as noble metals. Class 10 Chemistry Metals and Non Metals: Reactivity series: Reactions of metal with other metals: Reactivity series. The activity series is a list of elements in decreasing order of their reactivity. As example: zinc (Zn) replaces copper from copper sulphate solution. C10.2 Reactivity series. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series. Start revising A-level & GCSE with 7 million other students. Reaction will take place because Zn is above Cu in the activity series and is more reactive than Cu. III. Reactivity series of metals and non metals..... - 30542262 amansaroj25253 is waiting for your help. The elements which belong to Group VA, VIA, and VIIA are non- metals. GCSE » Chemistry » Metals - The Reactivity Series. Register Free. A metal with higher reactivity displaces a metal of lower reactivity. Non-metals react by gaining electrons - they are oxidising agents. A metal reacts with another metals and displaces them from their solution.
